To all whomi may concern.-

B it imwglmt we, CHARLES Dumas and JOHN- R. Plliurim, citizens of the United Stat,l 'tt'sifiin at HaskelLcounty of Passaic, and Stgt@ .ofV Tew Jersey, have inwned ,a new and useful Improvement in Machini-s for" Making Comb-Puwiler, of which the fallowing is afuil, dem. am! fxaut description, ref- `erene being had to the acmmpanying drawings, which forni a part of vthis speificatin.

Ourinveuiiun has fur its object the pmduc tion of a Iiiaviiim; by Vthe use of which semi powder ,may be fnrmed. We wili first describe the embodiment of our iive'ntiori illustrated in the accompany# ing drawings und than point out. tbe imsitiiii in he claims.

In the drawings, Figuriv is n side elevation of the anahne. Fig. 2 is aiongitudinal sectiun un b iin?I 2 2, Fi 3. Fig. 3 is .is transverse scctiun through t e cutting-mii.

Fig. 7 is an eievatinn showing a lmllied form of nuttin ruil.' Fig. 8 is fi pian vicw (if :istrip 5f mm powder.
